Nolli, Lanciani, and the Spatial History of Rome

Presenter: Kelly Mabry, Architecture

Giambattista Nolli’s 1748 Baroque Map of Rome remains one of the most engaging and accurate maps of the city ever created. Rodolfo Lanciani’s 1902 archeological map of Rome, based on Nolli, depicts the city as a series of layers extending from antiquity to the beginning of the 20th century. By carefully comparing these two cartographic sources, one can create a clearer understanding of Rome’s spatial history and how, among other things, Rome’s famous seven hills have influenced the city’s growth over the centuries. By using the geo-database software, ArcGIS, both the Nolli and Lanciani maps can be further geo-rectified with recent satellite imagery and data to achieve an even richer, layered, spatial understanding of the city. This enhanced layered approach opens new possibilities toward the understanding of Rome’s spatial history and its evolution over two millennia.
